Description

L. SESSLER.
CULTIVATOR.
APPLIUATION FILED JULY 1, 1912.
Patented Aug. 12, 1913.
1 c0. WASHINGTON. u. c.
IIITEU AEg CULTIVA'IOR.
Application filed July 1, 1912.
To (ZZZ whom, it may concern:
Be it known that I, LEONHARDT, SnssLER, a subject of the Emperor of Germany, and residing at Bottenweiler, near Zumhaus, in Bavaria, Germany, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.
This invention relates to cultivators of the kind in which rotary disks are made use of, and my improvement in cultivators of this kind relates to these disks, as is more fully described hereinafter. When working binding soil by means of the disk in question, the earth adheres to them and thus retard their rotation; furthermore, the wear and tear of the hubs or bosses of the disks is very great, which entails a frequent replacement of the said disks. I have overcome these drawbacks by making the disks annular and afiixing each of them to its axles by a plurality of arms extending radially from a sleeve-like hub held by the respective axle.
In order to make my invention more clear, I refer to the accompanying drawing, in which similar letters denote similar views and in which Figure 1 is a front view of my novel disk, the sleeve or boss being shown in section; and Fig. 2 is a horizontal section through the disk with its sleeve or boss, some adjacent parts being represented in plan.
Specification of Letters Patent.
Patented Au. 12,1913.
Serial No. 707,112.
The part is is the substitute for the disk before employed and is formed by an annular disk or a ring preferably of shallow section, as shown in Fig. 2. The central opening of the ring Z: contains a boss or hub in having radial arms 6 connected at their outer ends with said ring in order to hold the latter in place on a. sleeve a loosely disposed on the axle (Z. The sleeve a is prevented from lateral displacement upon the axle (Z by a pin f, and is furnished at its free end with a grease cup 0 for lubricatin said axle. The disk 70 is secured by a set screw to the hub a. and the latter rotates on the axle (Z.
It will be seen by reference to Fig. 2 that the disk 71: is annularly dished and that the inner and outer edges 70 and 7& lie in the plane a a of the face of the disk.
What I claim as new and desire to secure by Letters Patent is:
In combination, an annular ring-like cultivator disk, and a center hub structure for supporting the disk, said disk being annularly dished and the inner and outer edges of the disk lying in the plane a a. of the face of the disk, substantially as described.
In testimony whereof I atlix my signature in presence of two witnesses.
